Hi all.
To be clear, the instructions do not say "must" or "only" relative to using MTH mode or Wi-Fi to update the WIU firmware. Also, in the initial firmware release, LuCI doesn't leave the "system flashing" screen. Ever. Kinda goofy if you ask me. We just chose to live with it to get it out sooner. Don't worry, we know better.
Please understand that our objective is always to try and keep the scope of options narrow and use what we believe may be the most universal and understandable approach to tasks like updating firmware. Of course, the WIU is essentially a custom purposed Wi-Fi router. Most all normal Wi-Fi protocols and practices still work and apply. But, why explain all possible ways to update firmware and potentially confuse some when we can just provide a simple and direct path that gets the job done? Those more knowledgeable in Wi-Fi networking will figure out the rest as evidenced in this thread. And, we sincerely appreciate those of you sharing your knowledge. Thanks.
Like the entire Wi-Fi DCS system, LuCI will also continue to improve. You may have noticed how plain and utilitarian she is. Well, she's going to get a makeover and become much more attractive and easier to talk to. Here's a thought.....after being notified within your DCS app that a WIU firmware update is available why not just tap a button and follow simple onscreen instructions and be done? They call them smart devices for a reason.
Standby. Lots more to come.....
